Dan I don't know for sure, but they should be good to go. The ponds around here are froze, but I don't think it has been cold enough to freeze over Patoka yet. It got up to 37 or so today and 48 is scheduled for tomorrow and low to mid 50's for Friday. So iced up ramps should definitely not be a problem. Hope that helps and if you go, give us a report so we know how you did!
